SchemaValid is a free browser-based toolkit for structured data and technical SEO. It provides JSON-LD generators, a schema validator, sitemap tools and robots.txt utilities, along with tools for text and content, AI search, analytics, campaigns and other tasks such as IBAN validation. The validator checks either a live URL or pasted JSON-LD and reports an SEO score, errors, warnings and rich-results readiness. URL checks provide scorecards for 16 schema types, including Organization, Product, Article, Recipe, Event, FAQPage, JobPosting, Course, VideoObject and SoftwareApplication. Visitors can make five URL checks per minute. Pasted-code validation runs in the browser without uploading or storing the code or tying it to an account. Its AI Search Readiness Checker scores a page out of 100 across eight categories, reading the page and its robots.txt, sitemap.xml and llms.txt. A visual robots.txt editor offers a live preview for crawler rules, AI-bot access and sitemap settings. The tools require no registration, though the maker reserves the right to change, restrict or discontinue them.
